Not strong enough to remove virus. Like the other antivirus kaspersky may be i am wrong but it did not detect some hidden virus and some shortcut type virus causes from pendrive aur external hardrive. Sometimes plugin those pendrives b y mistken it doesnot remove virus and even though don't protect my laptop from lagging. SO if you can make it more strong enough to tackle those external pendrive virus, it will be better because google using worst antivirus mcafee the worst or i say wortest antivirus or in hindi kabaad or ghatiya antivirus. So goggle se virus ana aur easy ho jata h system k liye so please make your antivirus more strong to protect me and other from macafee antivirus or say macafee virus..
